I'm pretty surprised myself. Bassong and Nelsen will almost definitely be leaving and King and Gallas won't be able to play too many games, leaving Kaboul and Daws as the only reliable CB's.* I agree with Gutter Boy in that the management must have someone in mind to bring in. But does this mean that they don't believe Caulker is good enough or that he needs more experience because, based on what I have seen, he could do a good job. And he would get quite a lot of games thanks to the CL (hopefully).
*Is Dawson even reliable? I hope so, but his injury record this season may suggest otherwise.
Lets hope they have someone lined up. They have had 2/3 seasons to scout a long term replacement to King.
